SIGHT FOR FIREARMS.

Specification of Letters Patent.

Patented June 2, 1908.

Application filed October 1, 1907. Serial N 0. 395,375.

' disadvantage of a sighting device of this character is that the marksman has to direct his attention simultaneously to two'separate points, that is to say, he has to see that the upper edge of the sight mark on the mirror is in ine with the target and that the edge of the image of the rear sight mark in the mirror adjoins the edge of the front sight mark.

The object of this invention is to provide a sighting device in which the marksmans attention need be directed to only a single point, and with this in view the invention aims to provide a device in which the image of the rear sight mark in the mirror is larger than the front sight mark on the mirror and adapted to be placed concentrically with respect to the same, so that said image will sur- The front and rear sight marks are made of contrasting colors, so that when the image of the rear sight mark is concentric with the front si ht mark there is a clearly defined margin or edge around the latter, and hence the marksman no longer has to. direct his attention simultaneously to two points separate in space.

In the accompanying drawing, Figure 1 is a side-elevation of a rifle provided with a sighting device according to this invention, Figs. 2 and 3 are respectively a side-elevation of the mirror and a view as seen by the marksman, Figs. 4 and 5 are res ectively a longitudinal section and front-e evation of the mark-box having the rear sight mark arranged therein, Fig. 6 shows the mirror in elevation reflecting the rear sight mark, and Figs. 7 and 8 are similar views showing modified constructions in which the front sight marks are located wholly on the mirror.

In the drawing A denotes the mirror,

which is placed on the barrel at its forward end and which faces the marksman. On the face of the mirror and projecting above the same is a black disk d forming the front sight mark. This disk is secured to the mirror by means of a flange 5 extending over the top of the latter, there bein a rib 0 extending from said disk along said ange.

Themark-box B, whichcontains the rear I sight mark, is for the most part of the usual construction. It contains a glass disk (1., which is darkly colored, but provided with a light spot the image of which in the mirror A is ada ted to be brought concentric with the disk as shown in Fig. 6. The glass disk a is illuminated by means of a prism e. In place of this construction, the mark-box may e provided with a sheet-metal plate f form- 'ing the sighting shield, this plate being provided with a light sight mark g, as shown in Fig. 3. When the aiming must be articularly accurate the disk-shaped fiel of' the rear sight mark must be so large that its image in the mirror A, in spite of the perspective reduction, will surround the front sight mark with a light edge.

In Figs. 7 and 8 the front sight mark al is located wholly on the mirror surface, Whether it is surrounded by the image g? or g of a circular or triangular rear sight mark.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
